Winterize Your Sprayer

The following 5 steps will save you time and money!

  1. Run the pump until all liquid is pumped out of the system. Do not run the pump dry for more than 30 seconds. Then shut the engine off and fill the tank with clean, clear water. Pump the tank empty. If the sprayer is going to be stored for several days, the following procedure is recommended:
  2. Put 1 gallon of anti-freeze and 1 gallon of water in the tank. If temperatures are expected to be below 0°F, check the freeze chart of the anti-freeze and add antifreeze to recommended ratio for expected temperatures.
  3. Start the engine and allow the pump to operate just long enough to fill the system with the anti-freeze solution. This is accomplished when only anti-freeze solution is coming out of the spray gun. Close the spray gun and allow the pump to operate for 1 minute.
  4. Shut the system off and place in storage. This procedure keeps all the valves and other moving parts protected during storage.
  5. When you are ready to use the system again, start the engine and allow the pump to operate until all anti-freeze has been pumped out of the system. Do not run the pump dry for more than 30 seconds. Fill the tank with clear water and one bottle of ammonia-based cleaning liquid (approx. 1 QT to 100 Gal). Run the pump until this solution has been pumped out. Refill the system with clear water and pump the system dry once more. The spray system is now ready to go to work.
